The most fundamental problem in software development is complexity. There is only one basic way of dealing with complexity: divide and conquer.
About Me
25+ years of software development experience
Hi there! I am Kaj Lund.
I live on the Finnish northern west coast and have been working as a professional software developer since 1998.
During the past 10+ years, I've mainly worked with fullstack web development, mostly building backends and robust REST APIs using Node.js.
Lately, I'm back to focusing on Delphi backend programming alongside Node.js system integrations, database design, and modern web tooling.
